DOOR FOB BAKERS OVENS.l

To all whom it may concern Be it known that I, MORRIS W. JAcoBI,

a citizen of the United States, residing at Weehawken Heights, county of Hudson, 5 and State of New Jersey, have invented a new and Improved Door for Bakers Ovens, of which the following is a specification.

This invention relates to a bakers oven door of novel construction which can be readily iitted in position, and which permits an escape of the steam from theL baking chamber into the chimney whilev the door is open, and an escape of steam from the bakery into the chimney when the door is closed, se that the atmosphere and temperature of the bakery is correspondingly improved.

In the accompanying drawings; Figure 1 is afront view of av door for bakers ovens embodying my invention; 2 a cross .section on line 2-2, Fig. 1; ig. 3 a cross section on line 3-3, Fig. `1; Fig. 4 a longitudinal section partly broken away on line L1-4, 'Fig 3; Fig. 5 a perspective view of part of one of the side plates and of the cooperating block, and Fig. 6 a section on line 6-6, Fig. 3. i l

The frame of the oven door is of such a size and form as to snugly fit into the monthy 10 of the baking chamber 11. It iscomposeo or a tolJ plate 12 having depending rear flange 13, and front tiange 14, a pair of side p ates 15, and a bottom late l'having depending flange '17, said ottoni late abutting with its rear edge against the ront edge of the hearth 4plate 18. The door proper or leaf 19 is so hung to the' side plates `15' as to swin inwardly while being opened, and outward y while being'closed, abutting in its closed position a einst inclined fianges 2O of the side plates (g'g. 6). Means are provided for readily hanginglthe door to the frame, and removing it t erefrom, so that it can be fitted in position and replaced whenever necessary 4 6 with very little trouble. Tothis effect, each side plate ,15 is rovided near its top with a fonxardl opening shallow recess 21 adaptl ed' or t e .accommodation of a block 22, whichabutsi against front flange 14 of top plate 12. The thinned section 23 of the side i hte which forms the wall of the recess is provided with an eye or bearing 24 which opens intol a. forwardly extending flaring Ilot 25. Block 22 has a corres ending bearan may be remoi/ably secured to the wall 23 by a screw Specication of Letters Patent.

27. Protuberances 28 formed on wall 23 during the casting of the side plate, may be ground downto such an extent, While tting the parts, that block 22 will obtain a snug seat. squared as shown, and is extended laterallyv some distance beyond the door ,frame to carry the usual counterweight 30. At those points where the shaft passes through the bearings 24, 26, it is rounded, as shown, to

The shaft 29 of door 19 may be form gudgeonsl that are freely rotatable within said bearings. In order to hang the v door, its gudgeons 31 are passed through slots 25 into bearings 24, blocks 22 areslipped sidewise into the recesses 21 so as to become seated within the same flush witli the inner faces of side plates 15, and close up the slots 25, after which the blocks are secured tothe walls 23 by the screws 27. In this way the slots 25 are closed up bythe blocks 22, so that the gudgeons 31 of the door leaf become confined within the bearings.

The shaft 29 of the door 19 is fitted` to the latter some distance below the upper edge thereof, so as to form a top door section 19 above such shaft. lVhen the door is closed, the upper edge of this sectionengags the top plate 12, to form a tight joint, section' 19 swinging of course forward while the door is being opened, or swung inward, and` backward while the door is being closed or swung outward. Directly back of the front flange 14, there is formed in the top plate l2, a row of openings 32, extending preferably from side t0 side of the door frame. These openings communicate with the chimncy 33 in suitable manner, so that the steam and hot gases passing upwardly through the openings may freely escape. It is preferred however to connect the openings with. the chimney by means of the flue 34 of aA hood 35 that extends forwardly from the oven directly above the oven frame and which `thus constitutes means for carrying ofi' thestealn fromthe oven mouth, as well as from the hood.A A

'[hc correlation of the parts is such, that when the 'door 19 is closed (Fig. 3), the

vhowever the door is opened, its lop .si-climi 19 in swinging forward against tron( flange 14, will cut the opcnings'is all' the lmkcry vand place them into direi-t communica(ion with the back of the oven mouth and thus with the baking chamber 11. In this Way, the steam from the chamber llwill find through the openings a direct exitl to the chimney, so that the volume of steam flow-A ing into the bakery is materially diminished and the air of the latter is thus maintained in a pure and cool condition.

claim: 1. A baker-s oven door comprising a leaf having gudgeons, a door frame havlng side plates provided with recessed sections, bearslots opening ings in the recess-walls and into the bearings, said slotsbeing adapted for the passage of the gudgeons therethrough into the bearings, blocks adapted to be seated Within the recessed sections and close up vand al doorcarried in theframe and the slots, thereby confining the gudgeons within the bearings, and means for attaching the 'blocks to the side plates.

2. A bakers oven door comprising a. frame having a front opening, a chimney, means for connecting said opening to the chimney, having a section adapted to occupy a position at either side of said opening,.thereby connecting the opening either with the baking chamber and cutting it oli" the bakery, or connecting the opening with the bakery and cutting it off the baking chamber.
